"HEEL-ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 322,126, dated July 14, 1885.

(No model.)

' had to the accompanying drawings, forming a part of this specification, in explaining its nature.

Figure IV shows in elevation and section a portion of the upper part of a National Heel- Attaching Machine.77 Fig. 2 is avertical sec` tion showing the position of the breastingknife before it operates. Fig. 3 is a vertical central section through the breastin g device, its

support, and theheel, representing the position of the parts after the breasting is finished, but before the knife is withdrawn. Fig. 4 is a plan view of the top of the completed heel, and Fig. 5 is a vertical section of the completed heel.

The invention is an improvement upon that described in my application for Letters Patent dated April 25, 1884,r Serial N o. 129,212; and it relates especially to the operation of breasting. In said application I have shown the arrangement and combination in an organized machine of nail-driving, heelspanking, and heel`-breasting appliances. The device herein describedy is a substitute for the breasting apparatus described in said application, and is adapted to be used in combination with the nail-driving and heel-spanking devices.

Referring to the drawings, A represents a block attached to the arm a of the revolving head B. This block is either rigidly seA cured thereto, or has a post, a', which en` tends upward into a hole, a2, in the arm, and a spring, a3, surrounding the post for forcing the block away from it when the knife is not being operated. When this latter construction is used, it is desirable to attach to the block a presser-foot, c4, such as shown in Figs. 1, 2, and 3.

The block A hasa dovetail recess into which the dovetail projection of the knifeholdingblock C, projects, and the knife-holding block holds a straight knife, c, or knife having a straight Vertical movement. It is secured thereto by the bolts c passing through slots therein.

The knife-holding jblock C also carries one or more awls, D, for forming holes in the heel at the same time that the breastingknife is operating.

The revolving head also has the arm A', which supports the block carrying a gang or group of awls, the arm A2, which carries the block supporting a gang or group of drivers, and the arm A3, which supports the spankerblock and the top-lift holder.

It is quite necessaryr for certain classes of work to form holes in the heel-blank after the top lift has been applied to receive additional nails, sometimes known as top-lift nails, which are used for more rmly securing the top lift in place, or for purposes of ornamentation, or to improve the wear of the tread of the heel, and it is of course an advantage to form these holes at the same time that the heel is breasted.

The block supporting the breasting-knifeis provided with a horizontal adjustment upon the arm supporting it, and is locked in any desired place by the screw c2.

The movement of the block A is limited by the slot e and pin e, which enters it.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a heel nailing or attaching machine,

in combination with nail-driving devices for driving the attaching-nails by which the heel is secured to the boot or shoe, the reciprocating block C, carrying the supple-4 roe 3.
